This board appears to have the exact same Nordic module as Puck.js. Would we be able to get Espruino running on this board? What would it take (other than the flashing hardware).

I like the form factor of the Feather boards and the modularity between the various wings. But I always make sure to support Espruino by buying the official hardware as well. Long time backer of all the Kickstarters!

Yes, you should be able to. You could check the circuit diagram against the nRF52832DK, but if Adafruit have used the same pins for Serial RX and TX then you could use the existing nRF52832DK firmware for Espruino (http://www.espruino.com/binaries/travis/­master/).

Having said that, they have their own bootloader by the look of it, so you'd have to look into how exactly that works. It might be that if you just uploaded the firmware (not the softdevice or bootloader) region then it'd 'just work'.

If you programmed it via an external SWD programmer then you'd be sorted though - just shove the nRF52832DK firmware on there and you're laughing.

I might have a word with them and see if we can arrange a way to get it on the Espruino site - if there's a custom firmware in a format that can be uploaded with their bootloader then it'd be much easier.

I used nrfjprog from the Nordic Semiconductor toolset using the Nordic Development Kit JTAG output. The SWD (SoftWare Debugger) pins are on the center connector X1 (loaded on the Pro version). Adafruit schematic: https://learn.adafruit.com/assets/52793.

I think it would be great if there was a way to collaborate with adafruit, this specific product they have , combined with espruino would be epic, it is nice to have the usb and battery charging integrated. The feather footprint would offer so many awesome accessories that they have developed for their feather line. I have a couple of the mdbt42q breakout boards from the espruino store and they are pretty cool, but I plan on trying a project with a nrf52 feather so i can try to make an easy, clean build using some feather "wings" as they call them.

It would be great - I have tried to suggest it to them at several points in the past, but I'm afraid there just doesn't seem to be the interest in it. The maintenance thing that some other companies (RuuviTag, Seeed, Nordic, etc) are doing would be perfect - I guess I could try and revisit it with them now it's a bit more popular.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering: ![](https://www.google.co.uk/images/srpr/logo4w.png)That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
